We will use a small breadboard with 3 jumper wires to connect everything together, a SD card to store the information and a 3.7V LiPo battery to make our data logger portable. For more info on DHT22, see Adafruit's DHT tutoria l. We will also need a 4k7ohm pull up resistor for the data line and a 100nF capacitor to clean the noise in the power line. We will connect the power pin of the DHT22 to the VCC (3.3V) pin in our MKRZero. Arduino MKRZERO + Click Encoders + DeeJ + Neopixels + 3D Printing awesome PC volume controller. An unofficial place for all things Arduino Advertisement Coins. This sensor is easily available and very versatile. 569K subscribers in the arduino community. Second we will need a DHT22 temperature and humidity sensor. The problem is, that all three of these things are AVR specific so don't exist on the Arduino MKR Zero which is SAMD21 based.SercomDigging further, I found that the SAMD range of microcontrollers use a serial communication module or Sercom which can implement several types of communication.From Microchip App Note 2465AThe SAM D21 chip has 6 of. The small form factor and built-in SD card reader makes it a perfect choice for this project. In order to build the weather data logger we will use an Arduino MKR Zero board. Plug a battery, add a protective case and you will have a neat weather data logger that you can use in remote locations where no connection is available. You can use the built-in SD card reader of the MKR Zero to store the data. With this project, you will be able to create in a few minutes a temperature and humidity data logger.
